VACUUM COATING MACHINE MANUFACTURER

Plasma refers to the forth condition of matter. Plasma is a partially or totally ionized gas, thus, that particular gas condition in which neutral molecules, positive ions and free electrons are all present at the same time. In this case, plasma means low energy content: higher or lower energy content defines a "cold" plasma compared to a "hot" one. In this "status" any gas, even the most inert, acquires an extraordinary reactivity and is able to modify the chemical-physical characteristics of a surface.

Cold plasma is used for pre-treatment and cleaning of a substrate at low pressure (vacuum). This condition allows reactions to take place in a temperature range of 20 to 30°C, while in conditions of atmospheric pressure these are possible only at temperatures of hundreds of degrees. In fact, despite the low temperature of the gas, the temperature of the electrons is very high (from 20 to 50.000 K) due to the length of the free run of the particles. This makes it possible to treat organic material (for example plastic material), which do not tolerate high thermic loads.

The plasma of a gas is distinguished by its strong reactivity in particular conditions of pressure and in the presence of very intense electric fields triggered for example by DC generators, RF, MF, MW. The applied electric field must supply sufficient energy to the particles which permit a general ionization of the gas due to reciprocal collision. The gas flow dosage, the process pressure and the intensity of the electric field must balance the ionizing forces and the natural tendency of ionization decay.

The nature of a plasma varies according to the type of gas, or to the mixture of different gases, pressure of gas/gases, form of volume which confines the plasma itself and the type of electric field which supports and maintains the plasma.

The plasma of particular gases, among which oxygen is always present, allows oxidation to develop at a low temperature when it comes into contact with the surfaces to be treated, that is the formation of functional groups on the surfaces themselves which permit optimal conditions for total cleaning to be obtained. Plasma treatment is an ecologically clean and dry technology as it requires a low amount of consumption material, there are no solvents and does not require any disposal of by-products.

It is a treatment that allows the removal of surface material forming volatile products.

It can be used for the micro-cleaning of surfaces contaminated by organic compounds.

Changing the nature of the process gas and blending, makes it possible to achieve different surface characteristics.

It removes organic contaminants or residue layers

It improves surface tension, and therefore wettability of the surfaces, reducing the angle with regard to liquids at optimal values

It sterilizes

It cleans any surface (of any nature, geometry and dimension) and modifies its chemical and electrostatic characteristics.

All The plants designed and manufactured by Kolzer use plasma treatments in order to achieve surface chemical modifications prior to varnishing, gluing, bonding, coating and decoration.

Plasma polymerization PECVD

PECVD is a transparent coating with a barrier effect.

The growth of thin films onto a surface can be efficiently done through chemical reactions in vapor phase (Chemical Vapor Deposition, CVD) of components containing the element to be deposited.

Changing the process parameters, the precursors and the shape of the reactor, the PECVD technique makes it possible to deposit numerous materials.

Exposing natural and synthetic polymers to specific plasmas, makes it possible to obtain surfaces chemically different from the original ones.

The result is a new product, with the same mechanical and physical characteristics, but with different possibilities in interacting with surrounding matter.

This treatment is usually applied in order to improve adhesiveness and wettability properties of polymers allowing the transformation of a surface, from water-repellent to hydrophilic.

Vice versa the use of fluorine based gases transform the surface in a Teflon-like material, therefore having remarkable characteristics of hydrophobicity and oil repellency.

With PECVD technology you can achieve similar benefits on all surfaces, metals, alloys, polymer and plastics, wood, glass….

Research carried out by our technicians, the constant cooperation with our customers and the most important laboratories worldwide, have allowed us to tune dedicated processes for a wide range of fields of application, for example: characteristics of surface hardness with low wearing coefficient, grafting, anti-corrosion in acid and alkaline environments, water repellence, oil repellence, fireproofing, scratch-resistance, non-sticking, anti-printing and bio-compatibility, anti-stain effect and decrease of water vapor (anti-fog properties), etc.

The chamber is internally lined with stainless steel protection shields.

It is equipped with portholes for visual checking of the process and it’s thoroughly tested with a helium mass spectrometer to guarantee its perfect sealing and air tightness overtime.
